How can biotechnology be used to preserve biodiversity?

Unless the habitat of the endangered species is protected, all the technology in the world will not stop the extinction of organisms!  How do you recreate a tropical rain forest or the arctic tundra using biotechnology.  If a single species of organism is on the verge of extinction, one can use surrogate incubation of embyros in a less valuable animals (Grebe's zebra embryo was incubated in a quarter horse mare producing the rare zebra foal successfully).  Or we can collect the seeds of every plant in the world and store them in a safe place.  However there are seeds that must be passed through the digestive tract of an animal to get them to germinate.  Without the animals, the seeds may not germinate and grow.  Or they grow but the pollinators are no longer available.

So I disagree that biotechnology is the salvation of biodiversity!

Hmm..I wouldn't think that is conserves biodiversity if genes are beign transfered and moved around. Genes will mixed or expresses more/less..you get a different phenotype. So, in a way the gene you put into another animal will linger around and I would say you create more diversity...instead of just preserving it. We are creating new phenotypes of things that already exisist.

I guess Storage of the genetic information will help to preserve biodiversity but it is not being stored purely....there are alterations that can happen inside the host cell/transipient cell. And after generations the information might change on that particular gene...is might not be preserved through evolution. It's hard to tell....it's more of a gamble.
